Senate Majority Leader Mitch McConnell (R-Ky.) said Thursday after attending a classified briefing that he continues to support special counsel Robert Mueller‘s investigation into Russian meddling in the 2016 presidential election, including possible collusion between the Trump campaign and Moscow.

McConnell told NPR that Mueller’s investigation and a separate probe by the Justice Department’s inspector general into the FBI’s actions during the 2016 election will ultimately provide answers to a number of questions swirling around the presidential race.

“The two investigations going on that I think will give us the answers to the questions that you raise — the [inspector general] investigation in the Justice Department and the Mueller investigation,” McConnell told NPR.
